Teaching GraphQL : Lessons from a beginner
summary
Claims a compact mental model speeds novices from clueless to competent by mapping REST concepts to GraphQL primitives and highlighting specific false assumptions Tested by building example apps for Shopify storefront and admin GraphQL APIs and iterating with beginners The model uses concept maps (nodes edges resolvers) and shows concrete mechanics: one endpoint, schema types, resolvers implement logic, queries and mutations use POST bodies, response mirrors request, resolvers hold the action not the HTTP verb, common mistakes include thinking GraphQL is a programming language for graphs and confusing CRUD with HTTP methods
